twst first-years who are extremely impressionable, and have started to adopt their upperclassmen's little movement quirks.
deuce starts doing this thing where he'll reach his hand up, abruptly stop, and hastily put his hand back down, a bright blush going over his face. he only ever completes the action a total of one time, which ace is there to witness -- and of course, ace bursts out laughing when he realizes that deuce is trying to adjust his glasses like trey does, except deuce obviously doesn't wear glasses.
not to be outdone, deuce and yuu both catch ace saluting with a peace sign after they leave ramshackle. ace freezes mid-pose, which gives them ample time to realize why the gesture is so familiar. and as soon as it clocks, yuu and deuce proceed to mercilessly make fun of him for it for the next week, pulling up pictures of cater on magicam and and asking if they're secret siblings.
jokes on both ace and deuce, though, because before they know it, they're putting their hands to their chests and cocking their heads to the side like riddle does whenever he's feeling smug. and it's not until deuce and yuu have had their fun with ace's peace sign (which he will never do again (which is a lie, he totally will)) that yuu pulls up a bunch of photos, revealing that they've been doing this for months now, and they were just waiting for the right time to bring it up.
jack starts putting both hands behind his head whenever he's thinking just like ruggie does, and it's not until he catches epel looking at him oddly that he even realizes he's doing it. epel practically holds him at pen-point and asks what he's done to the real jack when jack puts his hand to the side of his forehead in a way that looks eerily reminiscent of what leona does when he's stressed.
soon after that, though, epel starts lifting his finger to the side of his face or lifting a whole hand whenever he's trying to make a point. they're such small gestures, but they strike untold fear into the hearts of his dormmates for reasons they can't understand -- until they see vil and rook striking the exact same poses when vil's lecturing epel about how to hold your teacup in the most elegant manner or rook's greeting someone he's stalked for the past two hours.
ortho's already inherited some of idia's attributes, so nobody thinks anything of it most of the time. then, in rare moment of shyness, ortho puts his hand on his arm, and everybody in his class starts flipping out, throwing chairs, and asking the universe why their only ray of sunshine is turning more and more like his gloomy brother with every passing day.
sebek gets a triple-whammy all in one day. while at lunch with the other freshmen, he puts his hand to the side of his face like silver does, puts his hand to his chin like lilia does, and even pouts like malleus does when yuu steals a bit of his macaroni. nobody mentions any of this to him, but yuu secretly takes pictures of it and sends them all to diasomnia.
yuu, of course, doesn't get out of this unscathed. in fact, they might have ended up the worst, because they slowly start to take cues from every upperclassmen/teacher they know.
they start beating their textbooks, rulers, whatever they have against their hand like it's a whip, in much the same way professor crewel does. they shrug with both hands outstretched now, sometimes looking like azul, sometimes looking like ruggie, and even sometimes looking like rook. one day, they catch themselves slumping their shoulders and shaking their head like idia does whenever he's tired.
the freshmen don't catch on very fast. when they do, they all agree that it's embarrassing, but they're too far gone to stop it now.
(the upperclassmen catch on pretty quick. if they're at all happy about it, they hide it well.)
